TURNING STAGE FOR THEATERS.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed July 20,1906. Serial No. 327,100.

1'0 all whom it may concern.-

Be it known that I, Max KAHANE, a subject of the Emperor of Austria, residing at Vienna, Austria, have invented certain new and useful Improvements in Turning Stages for Theaters, of which the following is a specification.

This invention relates to a turnable or rotating stage for theaters, a portion of the flooring of which is formed by two platforms arranged one behind the other suspended after the manner of a rotary swing and which may be replaced by two other platforms suspended in the same manner, so that the depth of the scene may, if required, be enlarged while the building up of another scene 1s in preparation on the other platforms.

The number of the platforms employed and the succession in which they are used may vary.

The accompanying drawings show an example of execution of the invention, with four platforms suspended after the manner of a rotary swing.

Figure l is a vertical section through the axis of the stage; Fig. 2, a plan view, and Fig. 3 a cross-section through a stage of the aforementioned kind.

A designates the stationary fioor of a stage having an opening a, through which may pass a plurality of platforms 1, suspended by means of hangers 4, pivoted on bolts 5, secured to supporting-arms 3. These arms form crosses which are keyed to a shaft 2, j ournaled in bearings I), mounted on uprights c on each side of the opening a. The shaft may be rotated at one or both ends by any welllmown means. Walls 6 serve as lateral shields against contact with any movable structural parts of the stage. Each platform is preferably provided with hinged edge portions 7, which may be turned up to diminish the size of the platform to permit them to swing through the opening a without danger of engaging the floor A, and these edge portions when turned down form a substantially continuous surface between the fioor and the platforms and between two of the platforms, as shown in Fig. 1.

In a stage of the described arrangement sever'alfor instance, four-decorations may be prepared previous to theperformances and then brought in front of the auditory in any desired succession. There are always two platforms simultaneously situated in the horizontal plane of the stationary floor of the stage, and the rear of each platform may be closed by means of a rear decoration in order to render the decorations of the rear platform invisible to the public. While a per formance is given on one of the platforms the decorations of the others may be changed.

If it is desired to employ two platforms simultaneously, using the whole depth of the stage, the rear decoration separating the front platform from the rear platform is removed.

The several platforms may be supported in their respective positions of rest in which they are used by any well-known supporting structures adjusted either by hand or automatically in order to give the platforms the required stability.

I claim 1. A stage comprising a plurality of revolving supports and platforms pivoted thereon, two adjacent platforms being adapted, when brought into the same horizontal plane, to form a substantially continuous stage equal in size to twice the area of one platform.

2. The combination with a fixed stage having an opening therein of a plurality of pivotally-mounted platforms movable through the openings, two of the platforms when swung into the plane of the stage adapted to close said opening.

3. The combination with a fixed stage having an opening therein, of a plurality of platforms, and a plurality of revoluble arms carrying said platforms, said arms arranged to carry two platforms simultaneously into the horizontal plane of the stage to close said opening.

4. The combination with a fixed stage having an opening therein, of a rotatable shaft mounted centrally of the opening be low the plane of the stage, a plurality of arms keyed to the shaft, platforms pivoted to the arms arranged to swing in pairs into the plane of the stage and completely close the opening therein.

5. The combination with a fixed stage having an opening therein, of a rotatable shaft mounted centrally of the opening be- In testimony whereof I have hereunto set loW the plane of the stage, a plurality of platmy hand in presence of two subscribing Witforms, arms radiating from the shaft pivotnesses.
